DUMP-CAR.

'Application mea July 14, 1920. serial No. 396,194.

To all whom t may concern.' i

Be it known that we, HOWARD L. BEACH and WILLARD J. FENDNER, citizens ofthe United States, and residents, respectively, of Mount Lebanon andPittsburgh, in the county of Allegheny and State of Pennsylvania, havemade a new and useful Improvement in Dump-Cars, 0f which the followingis a specification.

Our invention relates to railroad rolling stock and consists in a dumpcar of the type in which the car bodyis tilted on the car underframe todischarge its load to the side of the track. C

The bodies of such cars havea pivoting or rocking mounting on theunderframe which heretofore has been provided above the underframeholsters and beneath the body floor. The immediate result of such amounting is to materially increase the distance between the body floorand the railf and t0 increase the height of the center of gravity. Whilethis is unobjectionable in some classes of work and, at times, may evenbe an advantage, there are many operations where this additional heightis a serious disadvantage and one object of this invention is to providean eilicient lower mounting for a tiltlng body. l

In a dump car of this type, it is`usual to dump the body with airactuated cylinders and -acommon construction is to provide one or4 morecylinders on one side of the car for dumping the car-in one directionand a corresponding cylinder or cylinders on the other side for dumpingthe car in the opposite direction. An object of the present invention isto locate and connect all the cylyinders and dumping mechanism so thatthey will all coperate in dumping the car in either direction. l

The lowering of the car Hoor 1s especlally advantageous 1n a'dumpingflat car when used in road bed construction and maintenance of way asthe section hands can shovel dirt and ballast onto the car more easilythan if the floor was higher, and in the accompanying drawingsdisclosing our invention, we have illustrated such a car; Figure 1 beingside elevation of one end of thecar; Fig. 2 is a vertical, transversesection on line 2 2 of Fig. 1 and illustrating the'bolster and bodymounting thereon. and

and open upwardly and ,their bottom Fig. being a similar section on line3-3 of Fig.. 1 and illustrating the operating mechanlsm. Both crosssections show the body 1n one position in full lines and in anotherposition in dot and dash lines.

The frame bolsters are mounted on the truck holsters 1 and eachcomprises a portion of the underframe center sills 2, out- Specieationof Letters Patent. Pa'iented July 19, 192L i wardly extending wingsections 3 and a tieplate 4;. Wing sections 3 are dish shaped ortions,adjacent truck bolster 1, provi'e a track or rocker stand for rockers 5-upon whichvthe body sills 6 are mounted. The latter carry the car Hoor,directly and thru suitable crossbearers 7.

Sills 2 and 6 are of the common fish-belly type of girder which hasproven so satisfactor in railway car construction. essentlal feature ofthese sills is thelr substantial depth intermediate their comparatlvelyshallow end portions. To retain the advantages of these deep sillswithout detriment to the low mounting of the body rockers, we spacesills 6 laterally of the body a greater distance from each other thanthe corresponding spacing of the underframe sills 2. The spacing of thelatter is practically limited to the standard followed in carconstruction.

This arrangement permits the lower portion of the body sills to extendsubstantially below the plane of the top of the underframe sills so thatthe depth of the body sills is not limited by the depth (or` height)ofthe underframe sills or vice versa. This construction also rovides lasuitable space for operating equipment as hereinafter men-'f Each wing 3and its respective rocker 5" are provided with one or moreinterengagingl lugs, here shown in the form of spur gear teeth 8 and 9which mesh during the rocking movement to prevent sliding of th'e rockeron its stand. The teeth mesh with a rollingr contact which 'eliminateslfriction between n them. Each member 3 and 5 is recessed for 'thereception of theLopposing teeth ofl its coperating member -and 3respectively., The 0perating.mecl1anism is spaced from the bolster.androcke1s, Aas shown in Fig. 1.

Two cylinders 10 and 11,;operated -by fluid l pressure, are pivotallymounted on brackets v 12,- on they vunderfraine,"y ,by trunnions 13which are located just below the-body floor' and inside lofthe body.sills.

of the latter from each other` and from the v underframeA sills, affordsample room be- The spacing tween the adjacent body'and underframe sillsfor thepositioning of the cylinder and the operation ofits piston." Thepiston rods 14 and..15 are directed downwardly and connectV at 16 and'lrespectively with individual leversi18 and 19.

` Adjacent'levers 18 and 19 and ixedly secured to, theru'nderframe sills2, is a bracket 'member 20provided with pin bearing holes 21, 22, 23vand24; adapted to -receive the leverfulcrumlpins and 26. The outer endof each Vlever 18 and 19 is connected to the body byflinks27 and,2 8vpivoted to brackets i `29,whichfaremounted on'body s-ills 6- area wasreasonably large.

\ If `pin25 bel inserted `in vhole 21, as shown in `1 ig ;.3,'Iandfairaadmitted to cylinder v10, leverf`-18, koperating as, a leverof the first class, nwillfbe turned on its fulcrum to raise the-lefthand side. ofthe body as indicated in dot and 4dash lines'in Fig. 3. If,at the same time',.pin-26 be inserted in hole 23 and cylinder 11actuated. lever 19, operatingas- -equipment is highly advantageous.This'is especially true regarding equipment placed beneath the carI bodyas is'fdone in our present car and as wouldbe necessary ina fiat-car. 4l

It is obvious that iffpins 25Qandf-26-be shifted to holes 22and 24respectivelyf-the dumping action of the car will bereversed.

The center ofgravityI ofthe empty car" body and the point of support,oi' the point of contact between rocker and rocker stand,"

are cordinated so that the body' weight always tends to return the bodyto upright position. Therefore exhaust of air from the operatingcylinders is followed by automatic righting ot' the body and it is 4un-v'necessaryv to provide mechanism for return'- ing the body to uprightposition.

Vlie do not illustrate thc general piping system of this car as the'same does not form part of this invention except as much as is Y? shownvin F ig.v3. A supply line 30 has flexible connections 31 to eachcylinder and each connection is provided with a cock 32 so' that itsrespective cylinder may be cut out of 'the operating-line for repairs orother cause.

By supplying the two cylinders from a single' line, the operating fluidhas free circulationto both cylinders and Will operate as aydifferential medium to direct the greatest tpantity of fluid to `thecylinder. having'y el* greater piston displacementl whi'chfinthisconstruction will be the cylinderffon the rising side of the body.It will be understood that the pair of cylinders shown isduplicatedne'ar the opposite end of the car and other pairs vmayl beadded when necessary;v v 85 Having described a preferred embodiment ofour inventionin the above specification, we'claimzv 1.
